Comments removed from .d.ts file

[yankeeinlondon]

When I use bili to transpile my TypeScript source I notice that all comments are stripped from the .d.ts output which is a shame because those comments are part of the typings and can add a lot to library consumers. Is there a way to configure Bili to keep these comments in?

This is because of your project's tsconfig.json settings. TypeScript defaults to removing comments when compiling. This is from the auto-generated tsconfig.json file:

{
  // "removeComments": true,                /* Do not emit comments to output. */
}

Set removeComments to false in your tsconfig.json, and comments won't get removed from your declaration files. If you output min packages, your general comments will be stripped, and only your d.ts comments will be preserved:

yarn bili --format cjs-min --format esm-min

If it bothers you that .d.ts files can have comments removed at all, you can chime in here to lend your support to always keep declaration comments: microsoft/TypeScript#14619
